Main Features Include:
+ NOAA Electronic Navigational Charts (ENC)
+ NOAA Raster Nautical Charts (RNC)
+ NOAA Weather Map Overlays

Electronic Navigational Charts (ENC) are vector data sets that support all types of marine navigation.

ENC Charts Include:
+ Buoys, Beacons, Lights, Fog Signals, Radar
+ Natural and Man-Made Features
+ Services and Small Craft Facilities
+ Seabed, Obstructions, Pipelines
+ Depths, Currents
+ Port Features
+ Traffic Routes
+ Special areas

NOAA updates the ENCs for Notice to Mariners on a weekly basis (timing of their availability is not guaranteed).

The ENC charts displayed in this app does NOT meet federal chart carriage regulations for regulated vessels.

NOAA RNC charts are full-color, geo-referenced, digital images of NOAA paper nautical charts. All maps are available for download.

Weekly updates to the RNCs are done on a 'best efforts' basis. The timing of their availability is not guaranteed.

Since complete ENC coverage is available in all U.S. waters, vessels required to use ECDIS may NOT navigate with NOAA RNCs. RNCs are approved for use by IMO ECDIS mandated vessels only if adequate ENC data is not available.

NOAA RNCs DO NOT meet USCG chart carriage requirements for commercial vessels.

NOAA RNC are not intended to meet federal chart carriage regulations published in the Code of Federal Regulations. NOAA makes no representations that the RNC Tile Service or the RNC Tiles provided thereunder meet federal chart carriage regulations.

Users should consult the Code of Federal Regulations for current federal chart carriage requirements.

Buy this app. Totally worth it

This app is great and hopefully marks the beginning of the end of the 25 year chokehold Garmin and Navionics have held over the boating world. Every American has contributed to the costs of NOAA putting together map databases. And for years the big companies fought to keep the raw data out of the hands of the public. So now it is finally available but predictively difficult to manage downloading and using the RASTER maps. This program does the hard work for you so now you can use all of the NOAA maps for free, forever, for only the cost of this program. It still lacks the ease and functionality of the big players but the app will get better and better as more boaters use it. Really fun for loookingbst digital charts of far away waters without paying extra for more charts. Have fun.

Get it NOW!

If you’re on the fence, jump off and DL this app. It’s better than the description implies. If you have a question about it, email the developer. I did, and got a response within an hour. The app is easily the best $$ you’ll spend today. You will only have to spend it once, no subscription for updates like similar apps. I got this as a backup for my onboard plotter and paper charts.

Too slow to be useful

As I pan around, it’s taking my iPad Pro a really long time to render a particular screen. This slow tile-by-tile rendering of the image repeats every time I zoom or move around on the map. It’s so painful as to render the app unbearable.

I tried downloading all of the maps, too (which, as an aside, was a very frustrating exercise ... you should be able to just tap on maps in the list to start the downloads and let them progress concurrently ... the three modals per download meant that I had to sit down in front of the iPad for ~20 minutes to download all of the maps) and that didn’t solve it.

This app has plenty of data available, but it’s unwieldy.

In the developer response, he says “after downloading the maps, the tiles load instantly.” But downloading multiple maps is a clumsy affair. This should be streamlined, getting rid of all of those modal dialog/alert boxes.

So thank you for taking the time to respond, but I’d suggest you revisit this downloading process. It’s really quite cumbersome (esp if you want to download multiple maps).

Developer Response ,

Hi, after downloading the maps the tiles load instantly. You need to press the button in the top left that says ‘switch to offline mode’.

After viewing the tiles instantaneously after downloading, please consider editing your review. Thank you.
